Jim Harbaugh took direct aim at Green Bay Packers linebacker Clay Matthews on Monday, a day after Matthews made a point of roughing up San Francisco 49ers quarterback, Colin Kaepernick.

Matthews launched himself to Kaepernick and brought the QB down with a clothesline tackle after Kaepernick was well out of bounds. After Niners’ left tackle Joe Staley grabbed Matthews in defense of Kaepernick, Matthews took a few swings.

“I looked at it with my own two eyes and I could see two punches thrown to Joe’s head,” Harbaugh said, according to the San Francisco Chronicle. “Well, one punch and one open slap, which was just a…if you’re going to go to the face, come with some knuckles. Not an open slap.

“I think the young man works very hard on being a tough guy. He’ll have some repairing to do to his image after the slap.”
